When sent in a march without a Commander, your units do not benefit from Unit Bonuses, meaning that they are quite weak. To improve their bonuses, level your Commander up and do not forget to send him in attack marches.
FAQ: Can you nerf units?
No, units cannot be destroyed or dismissed through other methods than being destroyed in battles. Keep in mind that attacking Rebels will only injure your units.
